IMPROVEMENT IN DOOR AND GATE SPRINGS.

Specification forming part of Letters Patent No. 172,418, dated J annary18, 1876; application filed June 26, 1875.

To all whom it may concern:

Be it known that 'I, LEVI GALLAHER, of Businessburg, Belmont county,Ohio, have invented a new and Improved Grate-Spring, of which thefollowing is a specification:

The invention consists in combining, with a gate, a spring, slottedplate, slide, and dog, as hereinafter more fully described.

Figure 1 is partly a side elevation, and partly a sectional elevation,of my gate with the improved spring attached. Fig. 2 is a section of thepost, to which the auxiliary hinge-post of the gate is bolted, and alsoshowing the spring. Fig. 3 is a detail in top View, showing the springcontrivance for closing the gate. Fig. 4 is a section of Fig. 3 on theline a: m.

Similar letters of reference indicate corresponding parts.

A is the pintle portion, and B the arms, of the rod, on which the slatsare mounted for making the gate and hinging it. D is the auxiliary postto which the gate is hinged, and E is the one to which the gate closesand fastens. These posts are bolted to the permanent posts F and G bybolts H in holes I, which are larger than the bolts to allow of shiftingthem to adjust the gate, as may be required from time to time on accountof the sagging of the posts. In case the gate is to swing half round oneway in openin g the post D Will be bolted onto the face of the post Ffacing the post G; but in case it is to swing alike in both directionsit will be arranged as represented in the drawing. J is the spring in oron the post F for closing the gate. It extends up through a slot, K, ina plate, L, jointed to the top plate M on the slats, in such manner thatthe gate pushes the spring back when itopens, to enable the spring topush it shut. The spring also passes through a sliding platc, N, onwhich plate L works to he used for locking the spring back, in case itis not wanted to be used. The dog 0 swings up in front of the end ofthis plate to hold it back for so lockin g the spring. The button I?will prevent the dog from acting when turned upward for that purpose,but it only acts in case the gate is purposely swung back far enough forthe purpose, which is farther than is ordinarily required for passingthrough. Q, represents the reverse catch-plate.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The spring J and slotted plate L, combined with thegate, substantially as specified.

'2. The slide N and dog 0, combined with the slotted plate L, spring J,and the gate, substantially as specified.

LEVI GALLAIEIER.
